It was all right, but overdone at times. Perhaps even way overdone, and at many times. I had to resort to fast-forward.
On the upside, nobody was as annoying as characters of Ichigo Mashimaro, and so I managed to finish the series. And then of course Rize is #1. Although, personally, I liked Aoyama-sensei the most, even so. How does it work.
Art and animation were pretty, and somehow in keeping with the nature of the setting. Lots of primary colors.
Liked: It's a net win
